The bulbs can last 50 years.

LED light bulbs are already supposed to be energy-efficient, but Signifiy thinks it can improve on the formula. The company has released Philips Ultra Efficient LED bulbs that, as the name implies, use 40 percent less energy than the brand's usual LED options. The "advanced" LEDs and optics reduce the yearly energy cost to between 55 cents and $1.03 per bulb, Signify claims. For context, a Philips Ultra Definition 60W bulb uses an estimated 97 cents each year.

The new lights might also be helpful if you're trying to minimize waste. Signify estimates that the Ultra Efficient line has an average lifespan of 50 years, or more than three times the usage of Philips' standard LED bulbs. There's a real chance this lighting might outlive you.

The Philips range is available now as a Walmart exclusive. It starts at $10 for a 60W-equivalent A19 bulb ($17 for two) in soft white and daylight variants. A 65W BR30 bulb costs $11, while a 100W A21 light is $15. You're paying considerably more than you would for standard LEDs — a four-pack of Philips Ultra Definition 60W bulbs costs $14. However, Signify is clearly betting that the lower energy costs and increased longevity will ultimately save you money on top of being kinder to the environment.

The catch, of course, is that these aren't smart bulbs. You'll need to live with higher energy consumption if you insist on Philips Hue and don't want to use smart plugs. If that isn't an obstacle, though, you may see your energy bills shrink if you replace enough bulbs around your home.
